1989’s Look Into the Sun was the second volume in James Patrick Kelly’s Messenger Chronicles.
Mid-twentieth century Earth was thrilled when the alien Messengers made contact. The Messengers appear to have been less thrilled to have contacted Earth. The Messengers shared none of their hinted-at technological miracles. They didn’t even invite a divided Earth to join their commonwealth. As far as humanity goes, first contact seems to be a bit of a bust.
Phillip Wing is another matter. The Messengers are very interested in Wing.
